As the health risk presented by asbestos is transmitted through breathing the fibres only, it can be valuable to know the amount of airborne asbestos in a space.

To assess this, air monitoring is performed. This will involve an air pump with a filter membrane attached being set up in the space in question. The pump will run for a minimum of four hours. Once the pump has run, the filter is analysed at an IANZ accredited laboratory who will be able to indicate the level of asbestos contamination present in the air during the pump's run time.

There are a two different options for air monitoring:

1. Static air monitoring - The pump is set up in a static location in a room and tests the quality of the air in the room.
2. Exposure monitoring - The pump is attached to a person during their normal day, this gives an indication of if there is any exposure to the person throughout their day.

Air monitoring and clearance inspection associated with removal


The Health and Safety at work (asbestos) regulations 2016 have introduced requirements to perform several stages of inspections and air monitoring during the asbestos removal process. These break-down into several main sections: enclosure inspections, background air monitoring during removal, clearance inspections (stage 3 and stage 4) and air monitoring.

Our staff are able trained to the Australian standard for conducting 'Asbestos Assessment Associated with Removal.' We can perform:

• Enclosure inspections & smoke testing.
• Background air monitoring during removal (control monitoring).
• Stage 3 clearance inspections and air monitoring (after removal but while the enclosure is still in place).
• Final visual clearance inspections (with air and/or swab sampling if required) once removal is completed.
